What is it about _'s general knowledge in the liver cirrhosis ascites

What is it about _'s general knowledge in the liver cirrhosis ascites
At the time of active liver cirrhosis, often present the ascites. The mechanism that the ascites forms is a very complicated course, because this is by many kinds of pathologic factors, many kinds of internal organs, result that a plurality of links interact on each other. Summing up roughly has the following several respects:
1,The high pressure of portal vein: Liver portal vein and lower vena cava are also called the door vena cava, it is the connection place of liver and other positions blood circulation. Also the liver artery and intravenous only road that comes in and goes out of liver. The capacity of its pulse blood vessel bed of sound is basically equal in normal cases, the quantity of inputting the blood flow and outputting the blood flow is in equilibrium state. When the liver cirrhosis, because hepatocyte change the sex and necrosis, fiber organize hyperplasia, cause the blood vessel bed in the liver to be pressed, twisted, out of shape, narrow, has blocked the blood vessel, enable liver sinus extravasated blood, blood flow volume is reduced greatly, input is obviously greater than the exporting amount, make the pressure of vena cava of the door rise. Meanwhile, intravenous pressure of the capillary rises too, as time passes, reflux blockage of blood such as gastrointestinal tract, mesenterium, peritoneum, the blood vessel is penetrating to rise, the blood plasma composition in the blood leaks, has formed the ascites.
2,Low albumen blood disease: It is because the nutriment that the liver can't digest and assimilate the intestines and stomach formates albuminously. Because of the reducing of the serum albumin, the colloid permeates and presses to drop, ooze and form the ascites outside the blood plasma composition in the blood vessel.
3,Endocrine regulation: At the time of active liver cirrhosis, because the liver opposes the deactivation function of hormone of diuresis and fails greatly, its content rises, but make to urinate to reduce, can also cause edema and ascites.
4,Lymphocytic reflux obstacle: The lymphocytic circulation of the human body is also called the third cycle, means lying in the artery, intravenous, a circulatory system beyond the capillary. Normal people do not have it is circulated that the place is not lymphocytic, especially between liver sinus and hepatocyte, there is abundant lymphocytic liquid. Because of pathological change, the liver not only makes the pressure of vena cava of the door rise also make lymphocytically since the pressure is raised, in charge of expanding, lymphocytic reflux obstacle, make the lymphocytic liquid overflow, form the ascites.
